Shiny Penny Experiment

By Colie Haahr, CMNH Educator

We were surprised by how excited kids got about cleaning pennies when we offered this experiment as a drop in STEAM activity at CMNH! It does seem like a magic trick when you first see the pennies getting shinier almost instantly. 

This experiment is a good way to practice making predictions and observations, and it’s an easy one to do with materials that are available at home! For kids learning about money and currency, this is a great way to practice counting and recognizing the different coins as well. 

Materials:

  • Table cover of some kind (a trash bag works!)
  • Several pennies
  • Other coins- quarter, nickel, dime, coins from other countries if available 
  • Vinegar 
  • Salt
  • Bowl of water
  • Bowl for vinegar and salt mixture
  • Q-tips
  • Paper towels 
  • Optional: lemon juice, soapy water, other liquids you would like to experiment with

Directions:

  • One way to set this experiment up is to use a muffin tin or small bowls to offer several different liquids for kids to try. A small pallet for paint works well, too! 
  • Put the coins on a surface you do not mind getting messy- plastic plate, paper towel, or directly on the table covering, but you will want some paper towels or dish towels nearby
  • Allow kids to experiment with the materials to see what would work best to clean the different coins by dipping the coins in the liquid, and brushing them with a q-tip
  •  Ask what they think will work best, and why?
  • After some experimentation, guide them toward the vinegar or lemon juice mixed with salt. The salt works as a mild abrasive, and the acid in the vinegar and lemon juice react with the pennies to make them shiny and new looking
    • Important: rinse the pennies in water after cleaning them if you would like to keep them nice and shiny! They will oxidize and turn green otherwise. 
    • Fun fact: this is what happened to the statue of liberty, and why it looks green today! Kids did not dip it into a bowl of vinegar, but the statue is copper, and it turned green because of oxidation over time. 
  • Ask why the acidic liquids cleaned the pennies, but not the other coins? What is different about them? The pennies are a different color because they are made of a different material: copper!

What’s Happening? 

 Pennies are made of copper, and copper is shiny, but over time it becomes tarnished and appears black or brown because of copper oxide, which is created when copper bonds with oxygen. Acids mixed with salt help break down the copper oxide on the penny. Vinegar may remove actual dirt from the pennies and other coins because it works well as a cleaner! 

Extensions: 

Science Bob offers a few more experiments you can try using the same materials.

Scientific American offers some ideas for different liquids to use, and a more in depth explanation and method for advanced experiment-ers.

First Friends Songs About Bugs & Insects

By Meredith Brustlin, CMNH Educator

Even if it’s rainy and gross outside, we can PRETEND it’s Spring, right? That’s why I shared songs/rhymes about bugs & insects this week! 

Hello Song:

Hello it’s time to play
Let’s have some fun today!
Let’s clap our hands
And wiggle our toes
A hug...and a kiss...and away we go!

Hello (insert name here) it’s time to play
We’ll have so much fun...hooray! 

Open Them/Shut Them (action song)

Open them, shut them
Open them, shut them
Give a little clap-clap-clap

Open them, shut them
Open them, shut them
Lay them in your lap-lap-lap

Creep them, creep them, creep them, creep them
Right up to your chin-chin-chin

Open up your little mouth…
But do not let them in! 

Beehive (action rhyme)

Here is the beehive
But where are the bees?
Hiding inside where nobody sees!

Soon they’ll come buzzing out of the hive…
One! Two! Three! Four! Five!

Buzzzzzzzzzz!

I’m a little Beetle (bounce) 

I’m a little beetle and I wiggle all day
If you get too close to me I’ll FLY away!

I’m a little bumble bee and I wiggle all day
If you get too close to me I’ll FLY away!

I’m a little lady bug and I wiggle all day
If you get too close to me I’ll FLY away!

I’m a little dragon fly and I wiggle all day
If you get too close to me I’ll FLY away!

Sleepy Bumble Bees (song/movement)

See the little bumble bees sleeping ‘til it’s nearly noon
Shall we wake them with a merry tune?
They’re so still...are they ill?!
No! Wake up bumble bees!

Hop little bumble bees hop, hop, hop
Hop little bumble bees hop, hop, hop
Hop little bumble bees hop, hop, hop
Hop, hop, hop aaaaaaaand...stop!

“  “

Jump little bumble bees!

“  “

Dance little bumble bees!

Popcorn (prop song)

Popcorn, popcorn (Wave your scarf!)
Popcorn, popcorn
In the pot, in the pot (Hide your scarf in your hands)

Shake them, shake them, shake them (shake shake shake!)
Shake them, shake them, shake them
‘Til they pop! ‘Til they pop! (Throw scarf in the air!)

Scarf Opposites (prop song)

Wave your scarf up high,
Wave your scarf up high,
Wave it up high! Wave it up high!

Wave your scarf down looowwwwww
Wave your scarf down looowwwwww

Wave your scarf! Wave your scarf! 

Wave your scarf fast/slow

Wave your scarf in front/behind

Wave your scarf a little/a lot! 

Goodbye Rhyme (action rhyme)

This is big, big, big
And this is small, small, small

This is short, short, short
And this is tall, tall, tall!

This is fast, fast, fast
And this is slow, slow, slow

This is yes, yes, yes
And this is no, no, no

This is hi, hi, hi
And this is bye, bye, bye!

Ice Exploration!

iceexploration.png#asset:11929

By Meredith Brustlin, CMNH Educator

Materials Needed:

  • Bowl(s) or container(s) that are freezer safe
  • Fun items/trinkets to freeze (small plastic toys, rocks, coins, etc)
  • Food coloring (optional, if you want colorful ice)
  • Spray bottle
  • Salt

Directions (prep):

  • Collect small trinkets and items from around the house and place them in a bowl or container
  • Fill the bowl or container with water
  • Add food coloring, if desired
  • Freeze at least overnight (depending on the size of your container)
  • Fill a spray bottle with water & a few spoonfuls of salt, shake! 

Directions (activity):

  • Take the container out of the freezer and turn it upside down on a cookie sheet, tray, or large dish
  • Once the ice has unstuck from the container, remove the container and invite your young scientists to play!
  • Direct them to spray the ice with the spray bottle. You can also have some other salt available that they can use to help melt the ice. 
  • Try to free some of the trinkets! 

The Science:

  • There are so many angles that you can take for discussing the science of this project. 
  • The water: it changes from a liquid to a solid when we put it in the freezer! While you melt the ice with the salt water, it changes back into a liquid again! That’s two states of matter, can it become a gas? (Yes! Water vapor!) 
  • The melting: Salt lowers the freezing point of water. Ice melts faster when salt is added as the salt lowers the freezing point of the ice, this is known as freezing point depression. The more salt you add the lower the freezing point. This is why we use salt on roads in the winter to help melt the ice and make them safe! 

The following Wee Ones video is designed for preschoolers and is all about "Melting" and would make a good video to watch together while doing this experiment!

Make a Bird Kite!

by Meredith Brustlin, CMNH Educator

The craft I have to share with you today is making a bird kite! This is a really simple activity that you can do with a handful of household items - and it will (hopefully) supply your little ones with a whole bunch of fun.

This awesome activity was found on www.krokotak.com - browse their website for a variety of other fun activities that use simple materials you can find at home, mostly paper! 

Materials Needed:

  • Piece of 8.5 X 11 paper 
  • 2-3 Sticky notes 
    • Or pieces of colorful scrap paper and a glue stick or tape, I like the sticky notes because they are self adhesive!
  • Stapler, scissors, hole punch
  • Markers, stickers, any other decorations you’d like
  • String/ribbon/yarn

Instructions:

  1. Fold a piece of paper in half 
  2. Gently “swoop” down both sides to form the wings of your bird and attach with one staple
  3. Punch a hole on the bottom for the kite string
  4. Cut a sticky note to make a beak and tail feathers--feel free to add other decoration using markers
  5. Add some sticker eyes
  6. Attach the string - you’re ready to fly!

Polymer Science MAGIC!

Materials Needed:

  • Large mixing bowl or container (a casserole  pan would work!)
  • Plastic bag (I recommend quart size) filled ¾ of the way with water
  • A bunch of pencils or colored pencils--the sharper the better! 

Directions (prep):

  • Fill your plastic bag ¾ of the way with water 
    • You may want to fill a few because this experiment is very fun!
  • Sharpen your pencils
  • Prep the activity area with the bowl or casserole pan

Directions (activity):

  • Ask your young scientists if they think you can poke a pencil through a bag of water without spilling a drop (they will probably say “No way!”)
  • Hold the bag up over the bowl or other container
  • Carefully twist a pencil through one side of the plastic bag and then continue to twist through the other side
  • No water will spill!
  • Try it with the other pencils

Invite your young scientists to try on their own using bags of water and pencils

The Science:

  • Plastic bags are made of something called a polymer
  • Polymers have long strings of molecules that are flexible
  • When you poke the pencil through the plastic bag, it wiggles in between these strings of molecules and the molecules seal up around the pencil so that no water is spilled!

Extend the learning:

  • Spend some time looking on the internet for other household items that are polymers - you’ll be surprised by what you find!

Tinker Time at Home!

by Meredith Brustlin, CMNH Educator

Every week at the Children's Museum of New Hampshire we host a program called “Tinker Time”. Tinker Time is a drop-in program that emphasizes the importance of tinkering! Tinkering helps children develop fine motor skills, increase problem-solving abilities, and is an open invitation to foster peer relationships. 

What I love about tinkering is that it’s open-ended and no-fail. The carefully selected activities are designed to have many possible solutions and ways to explore. This means that children with different learning styles, who are different ages, and have different interests can all get something out of these activities. 

I usually set up the tinkering program with five different activity areas: Art Material Creations, Sorting, Building, Sensory/Texture Play, and Cause & Effect Exploration. I’m sharing one activity from each of these categories, but please don’t feel like you have to set-up all of them to have a successful tinker time! Set up one or two - use these activities as jumping off points and then tweak it to match the supplies you have at home or your own child’s interests - it’s totally up to you! 

Enjoy tinkering! 

Art Exploration: Sticker drawing prompts

  • Place round tickers (or draw round circles with different colors) on index cards or pieces of paper. Invite your child to use the placement of the dots to make a picture! 
  • Try putting the same configuration of dots on several pieces of paper and have a “draw-off” with the whole family - see how different your drawings are even though you were given the same prompt! 

Sorting: Color sorting

  • Gather lots of different art materials from around your house (markers, permanent markers, crayons, hi-lighters, colored pencils) and invite your child to sort them. 
  • Will they sort them by color? By type of art material? By size? 
  • Invite children to try and make a pattern using the colorful art materials! 

Building: Cup towers w/ manipulatives

  • Collect plastic cups from around your house
  • Find some small manipulatives - little animal or people toys. 
  • Build homes for the animals or build fences around them. Hide little people in the cups and guess where they are. 
  • See who can make the tallest tower! 
  • Build a tall tower and then throw a ball at it to knock it down!

Sensory/Textures: Cars on Salt

  • Sprinkle salt all over a cookie sheet or other container
  • Use toy cars, toy animals, or just hands to explore the salt and make designs! 

Cause & Effect: Is it magnetic? 

  • Collect small items that are either magnetic..or not magnetic...and place them in a container
  • Find a magnet on your fridge that is powerful enough to pick up some small items
  • For younger children: test and see which of the items are magnetic! How many items were you able to pick up using the magnet?
  • For older children: invite them to pre-sort the items into piles of items they think will be magnetic and ones that they do not think will be magnetic. Use the magnet to test their predictions!

Exploring Our Way turns 8!

If you were visiting the Museum on Sunday morning March 4th, you might have been surprised to see half a dozen golden Labradors Retrievers strolling around. These dogs, mostly 10-11 month old puppies, are in training to become skilled canine companion dogs. ‘Puppy raisers’ and their charges visited Exploring Our Way to share information with families about the Canine Companions for Independence Program, which provides trained dogs to work with an adult or child with a disability, including Autism Spectrum Disorder.

The Children’s Museum of New Hampshire’s Autism Partnership Program, Exploring Our Way, debuted in March 2010 after many months of planning with a dedicated committee of advisors. Since then, the museum has opened its doors one Sunday per month exclusively for families raising a child on the autism spectrum. Exploring Our Way offers a quieter, less crowded environment in which to explore museum exhibits with the goal of providing the best opportunity for a successful museum visit. Siblings are invited too, so the entire family can enjoy a fun outing together. 

In the safe and welcoming surroundings of the Children’s Museum children with Autism Spectrum Disorder explore at their own pace, become familiar with the museum’s exhibits, and may feel comfortable enough to increase the length of time of their visit.  We invite families to consider visiting during public hours, if their child is comfortable enough, and give them free admission passes in case they want to make the transition.

We also introduce families to new resources and services, like Canine Companions for Independence, by inviting representatives to come to Exploring Our Way and share information with parents. Check the Exploring Our Way page on our website and Facebook to learn more about upcoming special guests.

Exploring Our Way will not happen on April 1st as the Museum will be closed for Easter Sunday. We look forward to seeing you on May 6th!

Visiting Artist Week

By Meredith Lamothe, CMNH Early Childhood & Literacy Coordinator

I love art. I love going to art museums and looking at masterpieces—I always have. I’m pretty crafty and have managed to make some art-like creations. I enjoy coming up with activities in our Muse Studio and finding ways to make them about the process of art rather than the final product (a subject that deserves its own blog post!). As I sit at my desk right now, I see Experience Guide Amanda outside doing our “Chalk Art” kit—no visitors have joined her yet, but she’s happily drawing a lovely rainbow near the entrance to the museum.

There’s just something about art, isn’t there? It can be whatever you want it—or need it—to be. For Amanda right now, it’s a calm moment before she gets back to her many tasks inside the museum. I’m more of a crafter and get a lot of joy from giving finished crafts to people I love. Art can be purely fun (have you seen the projects where you throw water balloons at a blank canvas?!). Art, especially with kids, can be a great way to visually see some of the fascinating growth that is happening—from drawings of stick figures with arms coming out of their heads, to beautiful clay sculptures and beyond.

As fun as art is on it’s own, just for yourself, it’s also great to have skilled instructors help out sometimes. They open our eyes to different art forms we may not have thought about before, introduce new materials to use to create, and have an abundance of knowledge and encouraging words to share.

And what do you know, lucky us, we have five incredible instructors visiting the museum next week! We’re thrilled to announce our first ever Visiting Artist Week here at The Children’s Museum of New Hampshire.

We will have five wonderful local artists joining us for workshops the week of July 24-28, 2017. A few of these artists were guests at our “Visiting Artist Camp” last year and the final products that those campers produced were nothing short of remarkable.

Workshops will be from 11am - noon each day and are included with museum admission and free for members. Workshops may be best for children 6 years old or older, but would be fine for younger children with some help.


Monday, July 24th: Neva Cole

Neva, the Communications Director here at the museum, will encourage families to tear up, rip, cut and glue painted paper into collaged sea monsters! If a mermaid or pirate find their way into your scene, even better!

Neva is a multimedia artist and illustrator who is not the least bit ashamed to admit she spends a ridiculous amount of time with paint on her hands.








Tuesday, July 25th: Tess Feltes

Tess, the curator of Gallery 6 here at the museum, will be sharing some of her watercolor knowledge! Did you know all birds start from eggs? Of course you did! But! Did you know that bird paintings start with egg shapes?

Learn to draw and paint birds using simple geometric shapes with Tess!

Tess has illustrated numerous scientific books and articles and she is going to share some tricks of the trade.





Wednesday, July 26th: Cindel Lamothe

Cindel, an expert seamstress, will be here explaining a bit about the process of sewing—from patterns to fabric to putting it all together into a fabulous final product! What will be the final product of your hard work on the 26th? An adorable felt dinosaur that you can put on a pillow, apron, or frame and put on your wall!






Thursday, July 27th: Gina Perry

Learn how to draw imaginary creatures with children's book illustrator Gina Perry. She will show you, step-by-step, how to draw a Unicorn, Bigfoot, Loch Ness Monster, and a Mermaid. Watch out - you might even learn how to draw a Dragon!







Friday, July 28th: Francois Lamothe

Seacoast pastel & acrylic painter Francois Lamothe will be here to share his skills. Francois will be sharing some tips and tricks about painting flowers using chalk pastels! Be sure to come prepared to get messy—this unique art experience is sure to accidentally travel onto clothing (it’s washable!)





We hope you will join us for a day or two of Visiting Artist Week. It’s sure to be a lot of fun and you’ll learn some unique new skills as well.

Oh! In case you’re interested, some visitors have joined Amanda and her chalk outside now and have added frogs, fish, a yellow submarine, and some very large flowers alongside her rainbow!
